Well what you can do... I'm not sure if you can buy them but if you get a standard headphone jack, some cable and a left and right stereo RCA plugs, solder one end to the headphone jack, and the other end you split and solder a RCA plug to each of them. when i say plug i don't mean an actual plug but what the wii plug goes into. Put it in the Aux and there you go! need anymore info PM me!
